List the factors to be considered when selecting alternate routes and destination alternates. 

When selecting alternate route, you must be aware of:

Time and fuel required

Daylight hours remaining

Suitability and operational status of airfield (aerodrome plate AIP vol 4 and NOTAMS on IFIS)

Weather

A good way to remember how to multiply is to have a pet calculation. By setting up the pet calculation, all you have to do is change the numbers for the particular problem you are working. 

Example 1. Lets look at the 5 times table eg 5 x 2 = ?? and 5 x 3 = ??
Setup
	1. Find the 5 or 50 on the outside scale 2. On the inside line up the 1 or 10
Read off	( 5 x 2 = ?? )
	3. now look around on the inside for 2 and  4. read the answer on the the outside 10.
Read off	( 5 x 3 = ?? )
	5. now look around on the inside for 3 and  6. read the answer on the the outside of 15

read off '15'5. Inner find '3'

also you could easily read off  x4, x5 etc.

Setup	And without changing any thing you can also read off
Read off	( 5  x 14 = ?? )
	3. now look around on the inside for 14 and  4. read the answer on the the outside 70.
Read off	( 5 x 16 = ?? )
	5. now look around on the inside for 16 and  6. read the answer on the the outside 18.

6.26.6. Interpret information from Aerodrome Charts and Operational Data pages in the AIPNZ Volume 4.  

The AIP VOL4 contains information on aerodromes and procedures, as well as much more. Each airport in NZ has a page in the VOL4 with all the information you would need to visit there and fly the local procedures. 

An example of an aerodrome in VOL4 is as follows

The VOL4 symbols are as follows

6.22.4(b)  Aerodrome Chart. 

Aerodrome charts are published in the AIPNZ Volume 4 (link below)

These charts contain detailed information on many of the New Zealand aerodromes, including information such as frequencies, runway lengths, runway conditions and much more.

The Whakatane aerodrome chart is included as an example

 Calculate ETD and ETA in UTC given planned flight time details and reference time in NZST andor NZDT. 

To work out ETD, first we must convert our time of departure to UTC. Depending on the time of year, we would either subtract 12 or 13 hours (NZST / NZDT) from our time to get our ETD in UTC. 

To work out our ETA, first we must work out how long the flight will take to travel the distance with the given ground speed on the day, then add this time to our time of departure. We can then subtract the 12 or 13 hours to convert NZST or NZDT to UTC. 

6.14.2(c)  Head/tail wind; 

A Head wind or Tail wind requires the aircraft to be flown either into the wind or away from it.

With a tail wind, we are pushed from behind, therefore flying faster over the ground.

With a head wind, with have to fly against the wind, being pushed backwards, therefore flying slower over the ground. 

6.12.2(c)  Mean sea level (MSL); 

MSL is the sea level halfway between the mean levels of high and low tide.

6.10.2(c)  Fix; 

A fix is the geological position of an aircraft at a specific time determined by visual reference to ground features or reference to navigation aids. 

6.8.2(c)  Indicated Airspeed (IAS); 

Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator in the aircraft, displayed in knots.  

It uses the difference between total pressure and static pressure, to calculate a speed through the air
